Indeed.And pretty much all engines prior to the mid to late 1920s had iron pistons.Alloy pistons hadn't been developed enough to be reliable yet, mostly.Some of them (pistons) were pretty heavy - but those engines were mostly slow revving, and having a heavy piston saved a bit of weight in the flywheel dept, and made good use of the available torque. From ultra low revs in some cases - heavy flywheels/pistons makes the most of this.
